IPC: H04B3/36
Filed: 1962-10-31
Granted: 1963-09-13
Abstract: 983,935. Automatic volume control. SUBMARINE CABLES Ltd. Oct. 25, 1962 [Nov. 1, 1961], No. 39166/61. Drawings to Specification. Heading H4R. In a submarine repeater, the feedback path of the amplifier consists of a network which simulates the attenuation of a section of the cable and its variation with temperature and frequency. A length of cable has its attenuation proportional to the square root of the frequency and its temperature coefficient of attenuation half of the temperature coefficient of resistance of the metal of which it is made. A ladder network of series resistors and shunt capacitors also has these characteristics and if this network is included in the feedback path of a repeater amplifier it will compensate for the changes in attenuation of the cable due to variations in frequency and sea temperature. The construction of a repeater is described in which the valves are surrounded by heat conducting members connected to a heat sink held in contact with the repeater housing, while the feedback network is enclosed in a copper box connected to a second heat sink also held in contact with the repeater housing so that the network is kept at sea temperature. The resistors of the network are wire-wound components preferably made of platinum.

[Also in Group XV] An apparatus for use in securing a skin to a core comprises a container with a mass of rollable bodies therein and means for applying pressure to the rollable bodies so that when an assembled skin and core are submerged in the mass of rollable bodies and pressure is applied to the mass the skin and core will be forced into intimate contact and the mass will exhibit the characteristics of a solid. The mass of rollable bodies is defined as a mass of discrete rollable material having a low critical angle of repose and low surface friction, the material being refractory or inert to solvent or cement used. In one embodiment a mass of steel balls 14, Fig. 1, is provided in a metal box 10 having a plate 16 in its open end which is forced inwardly by a wedge 17 between the plate and a bridge 18. The balls surround an assembled sheet-metal skin and aerofoil section blade, e.g. for use in a gas turbine, at least one of the surfaces in contact being coated with brazing metal and flux. The apparatus is heated in an oven to effect brazing and after removal from the oven the pressure may be increased by driving the wedge further tmder the bridge. In a further embodiment a metal box 25, Fig. 2, with perforated walls and open top is supported in an open frame 30. Side walls 28a, 28b of the box have rectangular apertures 35a, 35b therein and within the box and parallel to the side walls are loose plates 36a, 36b with apertures 37a, 37b of the shape of the assembly to be brazed. The plate 36a is in contact with its adjacent side wall and the plate 36b is spaced from its adjacent side wall by a channel 39 having an aperture corresponding to that in the wall. Steel balls in the box are acted on by bars 43-45 pressed by individual wedges 46-48 and the assembly to be brazed is passed into the box through the apertures 37a, 37b before pressure is applied by the wedges. Brazing is then effected as before. The balls may be of glass, ceramic or silica and the apparatus may be used in cementing a sheet of plastic or fibrous material to a core of another substance and the apparatus may be of material other than metal. The Specification refers to brazing a metal skin to a grooved or fluted core to provide a gas turbine blade with passages for cooling air.

Abstract: 745,913. Automatic steering control systems. BENDIX AVIATION CORPORATION. Jan. 15, 1953 [Jan. 23, 1952], No. 1261/53. Class 38 (4). The invention is applied to an aircraft automatic steering system of the type described in Specification 662,831, in which alternating current signals produced by an earth inductor compass 22 upon course deviation control, through a valve amplifier 31, a follow-up servomotor 33 operating an induction device 34 producing an A.C. signal corresponding to course error. This signal is combined with the signal from the pick-off of a rate of turn gyro 23 and applied to an amplifier, comprising valves 41, 49, 55, the output of which controls an A.C. servomotor 57 operating the rudder 19 to restore the aircraft to its course. A limiter 60 of the type described in Specification 693,085, [Group XL (c)], limits the maximum value of the A.C. signal applied to valve 49. One or other of two negatively biased diodes 80, 81, depending on the phasesense of the signal, becomes conductive at the limit to shunt the output circuit of valve 41 and prevents any further increase of the signal applied to valve 49. Bias for the diodes is provided by a full-wave rectifier, including valves 69, 71. - To provide a limiting value of error signal which increases with increasing altitude the A.C. supply to the bias rectifier is varied by a potentiometer 130 adjusted by a follow-up servomotor 117 controlled by the pick-off 111 of a bellows unit 101 which is responsive to altitude and of the type described in Specification 662,918. A bellows unit responsive to aircraft speed may replace that responsive to altitude to decrease the limiting value of error signal with increase of speed.
